Then you are not running a 'standard shell', but some sort of local hack and/or wrapper: kobe-> ssh server "echo 'hello world' > foo" kobe-> ssh server "od -c foo" 000 h e l l o w o r l d \n 014 kobe-> echo hello new world | ssh server "dd >> foo" 0+1 records in 0+1 records out kobe-> ssh server "od -c foo" 000 h e l l o w o r l d \n h e l l 020 o n e w w o r l d \n 034 kobe-> I'm sorry, but I don't think you can get effective "help" from the FreeBSD lists. You will have to ask for specific guidelines and help from your hosting provider. Anything else will be guesswork and may break without any sort of notice in the future, when your host decides to install a "new" "security fix" to their custom shell. - Giorgos ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I want to append the contents of a local text file >>> to the contents of a remote text file, over SSH. : Andrew Pantyukhin wrote: > cat file1 | ssh [EMAIL PROTECTED] "dd -of file2" That will replace the contents of file2, not append it. Also it should be "dd of=file1". However, you can use "seek=n" to append, like this: cat file1 | ssh remote "dd of=file2 seek=n" ... where n is the length of file2 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
